STUFFINGf-BOX FOR WORKNG BARRELS F WELL-PUMPS.

Specification of Letters Patent.

Application filed April 24, 1911. Serial No. 623,079.

To all 'whom it may concern: I

lle 1t known that we, l`)ANiIn.,DA1-InLs and Lrsnn l. Bimenes, both citizens of the plunger rod United States.y residing at Los .-"inafelesg4 in the f fountv ot Los Angeles and State oi California, have invented a new and useful Stalling-linx tor lllorking Barrels of -Well- Pni'nps, ot which the following is a specitication. i

This invention relates to .f stuiting box for the working barrels of well pumps., and the main object of the invention is to provide an improved construction of stuffing box which is readily accessible for inspection or reni-iwal of thc packing when necessary.

t'lther objects ot' the invention will appear hereinafter. l

"the accompanying drawings illustrate 'the invention, and referring thereto:

Figure 1 is a perspective of the stuttng box in open posit-ion. Fig. Q is a Vertical section ot the stuffingI box in closed position. 1 designates the internally screw-threaded upper end of a Working barrel or cylinder of a Well pump and 2 the externally screwthreaded upper head thereof, said head being bored as at 3 for the passage of the or polish rod 4. Said head 2 is formed on its upper endwith a recess 5 for receiving the packing indicated at 6, said packing being compressed b v a gland member 7 which is bored to receive and tit on the polish rod and which slides within the recess 5 and is held down therein b v a clamping means hereinafter described. The gland member is provided with a cross head or enlargement 8 atv its upper end having laterally extending arms 9. said arms beinpr provided with notches or 4slots 10 to receive bolts 11, said bolts being hinged or pivoted to bitnrcated brackets 12 on the side of the barrel head :2 by pivot pins 13. Nuts 14 screw on the bolts 11 and are Jformed with peripheral portions 15 to adapt the nuts for manual operation. The. arms 9 ot the gland member are further provided Wit-h ledges or ilanges 16 at their outer ends., serving as seating guides and retaining stops for the nuts 14 when the nuts are in clamping position.

By unscrewing the nuts and turning the clamping bolts 11 down to position shown in Figil, the gland member is released and may be slid up as indicated in said figure, leaving the space or chamber 5 free or open at the top for insertion or repair of the packing. lt will be noted that in this position there is no obstruction to access to the packing from all sides. The packing having been pnt in place.v the gland member forced down on top of the packing and the bolts 11 are then turned up so to enter the slots 1t), the nuts 14 being at this time screwed out far enough to allow them to pass over the flanges 16 on the arms 9 and `when the bolts have been moved into the slots 10, the nuts 14 are screwed down tight. against the top of the head ot the gland member7 forcing the gland member tightly againstthe packing and compressing the packing to tighten the stelling box. 1n this position ot' the parts, the nuts 14- extend within the flanges 16, so that, even if Athe nuts become jarred loose to some extent., the;7 are retained in engagement with the head 'ot the movable gland member by these flanges acting as stop members to prevent the bolts from moving outward.

What We claim is:

A stutling box for the Working barrels ot' well pumps, comprising a barrel head formed with a recess for receiving the packing, and with bifurcated brackets. a gland member formed with a cross head having slotted arms provided with flanges servingr as seat-ing; guides and retaining stops snrmounting the ends of the arms, screw threaded bolts. pivot pins hingringr the in ner ends of the bolts to the bit'nrcated brackets ot' the barrel head, and nuts on the bolts having peripheral portions adapting the nuts for manual operation.

"ln testimony whereof, We have hereunto set our hands at Los Angeles, California, this 17th clay of April7 1911.
